(S09E05) This was the week the Blue and Yellow teams have been waiting for. After four weeks at home, working out without their trainers, both teams were back on campus to see which would be allowed the chance to return to the show. It came down to which pair had the highest percentage of weight loss.

But before they got on the scales, Bob and Jillian treated them to their first -- and for one of them, their last -- "Last Chance Workout." I couldn't help but feel for the team that was going to be heading home again. Twice they'd come to the Ranch to participate in 'The Biggest Loser,' and twice they'd come up short. At least they still had the chance at that "At Home" prize.

This week also saw Alison handing out immunities like they were going out of style, as well as a two-pound penalty to the team to finish the week's challenge last. I'm a huge proponent of this element being added, as it keeps the incentive on the contestants to give it their all until the finish.

(S09E01) That was fast. It seems like just last month we were crowning Danny "The Biggest Loser," and yet we're back at it already. The series returned to the "Couples" format for this ninth season, but that didn't stop them from finding even bigger contestants to throw at Bob and Jillian.

In fact, that was one of the first things the trainers talked about: how hard they were going to have to work to beat these guys into shape. Five contestants are weighing in at over 400 pounds, with one smashing Shay's record of 476 by coming in at 526 pounds. Two of those contestants are a set of twins weighing in at nearly a thousand pounds combined.

If being the biggest combined group ever wasn't embarrassing enough, the first thing these contestants learned was that their first weigh-in wasn't going to be at the Ranch. It was going to be in their hometowns. Outside and in front of all their friends and families. Welcome to The Biggest Loser.
